The methods for turning theenergy of coal directly into electric currents, I believe,have not yet been put into application. The subject ofcylinder condensation is one that has always been promi-nent in the study of the steam-engine. Before the time ofJames Watt, as you are all aware, at every stroke thecylinder was tilled with steam and then it was cooled downby pouring water on the outside or by admitting waterinto the inside, so that whenever the steam was admittedit found the cylinder cool. A large part of the steam ad-mitted at every stroke was turned into water at once onadmission, and some of it was doubtless turned backinto steam during the stroke, but much of it went out aswater in the end. Walt introduced the independent con-denser by means of which Ihe steam is removed from thecylinder without cooling the latter down as it was cooledbefore ; and yet, it is still believed that a very considerable. FOOT-BRIDGE AT BEDFORD PARK STATION. has been built, which is shown in the sketch, and whichharmonizes well with the station and its surroundings. The bridge is a single span ol 60 ft.; the two plate gird-ers are supported on two columns at each end. The gird-ers, which are spaced 8 ft. 6 in. apart between centers,form the railings, and the floor is carried on the lowerflanges. The stairways on either side are supported bycast-iron columns. The bridge itself and the stairwaysare covered by a roof of ornamental design, carried onlight iron columns. This station, it will be noticed, is fenced in, and fencesare placed to prevent persons from crossing the tracks ona level. This is the general practice followed on the Har-lem line at the suburban stations. In addition to the usual local traffic at this station,there is in summer a large number of passengers goingto and from the Bronx Park ; this is likely to increase, asthe park becomes belter kno
